Greater Yellowstone

There are so few large, nearly intact networks of wildlands left on earth. Greater Yellowstone is one of the last.

Greater Yellowstone is defined by blue-ribbon trout streams, grizzly bears and the longest wildlife migration corridor in the continental United States. But these treasures are now threatened by expanding energy development pressures and growing populations.

At Wilderness, we're working to protect this iconic American wildland from these threats and preserve the landscape's natural and human benefits.

During 2015, Gov. Walker reversed course and allowed these projects to continue spending money on studies.
